Preparation process of high-strength porous ceramic material
The invention discloses a preparation process of a high-strength porous ceramic material. The process comprises the following specific steps: preparing an initial material mixture, preparing a prepared raw material, preparing a green body and sintering to form the porous ceramic material. According to the invention, a modified material mixture is added into the initial material mixture so that large particles in the initial material mixture are connected through aerogel, and carbon nano foam is added in the preparation process of the modified material mixture to be stirred and mixed, so that the overall density is further reduced, the porous ceramic material is lighter, meanwhile, the dosage of the preparation material is reduced, and the production cost is reduced. Graphite fibers are added in the process of preparing the initial material mixture, so that the strength of the subsequently prepared porous ceramic material is improved. A ceramic pressing machine can press and generate aplurality of ceramic blanks at a time, full automation is achieved, the working intensity of workers is reduced, the production efficiency is improved, and the ceramic pressing machine is suitable forbatch production of porous ceramic materials.
本发明公开了一种高强度多孔陶瓷材料的制备工艺，该工艺的具体步骤包括初始混料的制备、预备原料的制备、坯体的制备以及烧结形成多孔陶瓷材料，本发明通过向初始混料内添加改性混料，使初始混料中各个大颗粒之间通过气凝胶进行连接，通过在改性混料制备过程中添加碳纳米泡沫搅拌混合，进一步降低了整体的密度，使该多孔陶瓷材料更加轻质化，同时减少了制备材料用量，降低了生产成本；在制备初始混料的过程中添加石墨纤维，提高了后续制备的多孔陶瓷材料的强度；本发明中的陶瓷压制机单次可以压制生成多块陶瓷坯体，完全自动化，降低了劳动人员的工作强度，提高了生产效率，适用于对多孔陶瓷材料的批量生产。
